for the mass, a fault the magnitude of which is greater than the larger of these two values: - one tenth of the magnitude of the maximum permissible error for the measuring system and for the measured mass, - the minimum specified mass deviation. For the price to pay, the price corresponding to the significant fault for the mass. The following are not considered to be significant faults: - faults arising from simultaneous and mutually independent causes in the measuring instrument itself or in its checking facilities, - transitory faults being momentary variations in the indication, which cannot be interpreted, memorized or transmitted as a measurement result, - faults implying the impossibility of performing any measurement.
